Specification of Letters Fatent.

Patented Jan. to, 1922.

Application filed. October 20, 1919. Serial No. 331,964.

To aZZ w 710m it may concern Be it known that I, GEORGE L. MAsoN, a citizen of the United States, and a resident of l Varehouse Point, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Serving Spindles, of which the following is a specification.

This invention relates generally to serving spindles or heads for winding or wrapping one strand about a second strand or core of the same or a different material and has particular reference to the construction and arrangement of the spool assembly which carries the covering strand.

It is the aim of the invention to provide an improved spool assembly for serving spindles which is simple in construction and relatively light in Weight, which is of such diameter that the covering strand wound thereon will not set, and which is of sutficient strength to resist the strains to which it is subjected when the serving-spindle is operated at high speeds.

In the accompanying drawing, I have illustrated my improvements applied to serving-spindle invented by myself and George M. Montgomery and disclosed in an application filed by us on Oct. 20, 1919, s erial No. 331,816, now Patent No. 1,386,350, patented Aug. 2, 1921, but it is understood that the present disclosure is by way of illustration only, it being evident that my improvements maybe used on serving-spindles of other types than that shown in the drawing.

The spool assembly forming the subject matter of the present invention and comprising the sleeve 10 and the spool 11 is shown, for illustrative purposes, as rotatably mounted on a spindle a carrying a flier having a pivoted thread guide 0. The spindle a is journaled on a non-rotatable tubular thread guide a? through which the strand forming the core of the composite thread passes.

' Serving spindles when employed to wrap or wind a metal ribbon about a thread or core of fabric are operated for the purpose of economy, at relatively high speeds, and therefore the spool assembly should be'of small mass but sufiiciently strong for the purposes in hand. At the same time, the diameter of the cylindrical portion of the spool upon which the metal ribbon is wound must be sufficiently large to prevent the metal ribbon from setting.

In accordance with the present invention, the cylindrical portion of the spool 11 is relatively thin and is spaced from the sleeve 10 by means of projections or flanges carried by the sleeve or spool. In the preferred embodiment, the sleeve 10 tapers down toward its forward end and has adjacent its rear end a circumferential projection or flange 12. The internal diameter of the cylindrical portion of the spool is such that the flange 12 will have tight sliding fit therein. The forward end of the spool has an end wall or internal flange 13, the opening through which is but very slightly greater than the forward end of the sleeve so that when the spool is slipped into place the flange 13 will have a wedging fit on the forward end of the sleeve. When the spool is in position, the flange 12 is slightly spaced inwardly of the open or rear end of the spool.

It will readily be seen that the spool is of relative large diameter and is light in weight, but due to the heads at the ends of the spool and the flanges 12 and 13 the spool is of sufficient strength to resist centrifugal forces tending to distort the same. 7

It is of course obvious that my invention is susceptible to various modifications and changes which are within the spirit of my conception without departing from the scope of the following claims.

I claim as my invention:

1. In combination, a rotating spindle, a sleeve positioned thereon, a spool entirely supported by said sleeve, and having a eylindrical portion of greater diameter than the external diameter of said sleeve, and in terengaging means adjacent each end of said sleeve and cylindrical portion of the spool for holding said sleeve and spool in spaced relation.

2. In combination with a rotating spindle, a thin walled sleeve journaled on said spindle and having a circumferential flange.

and provided with a peripheral flange adjacent its larger end, and ainetallie spool havinga cylindrical portion slidably receiving said flange and provided with an internal flange having a tapering fit on the smaller end of said sleeve. I
